In the whole macaroni production line, the whole production process is realized through the combined application of multiple equipments. The single screw extruder was used to produce the macaroni with medium extrusion and low expansion.
When the single screw extruder works, the material enters the extruder. The screw screw propels the material forward in the closed chamber, and feeds the material all the way to form the axial flow. Because of the arrangement of screw rods, the compressed cavity of raw materials is compressed and the mechanical friction with screw, barrel, and the interior of the material is intensely extruded, stirred and sheared. As a result, the material is further refined and homogenized to form a liquid fluid. With the gradual increase of pressure, the temperature rises correspondingly, and is high. Under the conditions of temperature, high pressure and high shear, the physical properties of materials change. From powder to paste, starch maturation, protein denaturation, fiber degradation, refinement. When paste is extruded from the die hole, the material is limited shape by abrasives to produce various shapes of macaroni. Material after maturation has better palatability and boiling resistance.
Use precautions
1. Sudden shutdown during operation:
It is not compulsory to start, should immediately check the shutdown problem, power or equipment itself power off, shut down the heating system. Look at the problem. If the power supply is cut off for a long time, the die body should be removed. If the power supply is not removed for more than half an hour, the equipment itself should be checked for overload. No overload phenomenon recovery circuit, see the frequency converter fault code. Solve problems in time.
2. Do not put foreign matter in the inlet and outlet or put your hand in to prevent the equipment from being damaged.
3. The protective shield should not be detached during the operation of the cutting knife to prevent hand injury.
